ROTARY APPARATUS OR PLOW FOR TREATMENT OF GROUND.

SPECIFICATION formingpart of Letters Patent No. 704,857, dated July 15,1902.

Application filed January 9,1902. Serial No. 89,086; (No model.)

To all whont zit puny concern:

Be it known that I, ANDRE OASTELIN, engineer, a citizen of the FrenchRepublic, residing at Paris, department of Seine, France, (havingpost-office address lTRue St. Florentin, in said city,) have inventedcertain new and useful Improvements in Rotary Apparatuses or Plows forthe Treatment of Ground, of which the following is a specification.

The present invention has for its object improvements in appliances forthe treatment of land by means of which machines-such as plows, barrows,hoes, diggers, and the like, to which a simple rotary movement isgivencan be replaced by rotary tools operating the attack on the groundin a quite difierent manner than the above-named machines while havingamovement of rotary.

In apparatus according to my present invention the tools are arrangedaround their axis of rotation. One part of these tools attacks theground and the other part serves for throwing the material eitheroutside the furrow formed by .the tool (in the case of plows, harrows,and the like) or inside the said furrow in the case of hoes, diggers,and the like.

My invention is especially applied to the kind of machines wherein theattack on the ground results from a rotary'movement, producing acontinuous or discontinuous furrow, for the purpose of turning up theground, shaking, removing, or hoeing the same, or removing superficialvegetation therefrom.

In order that my invention may be fully understood, I will proceed todescribe the same with reference to the accompanying drawings, of whichFigure 1 is a side view of a rotary plow according to my invention in aplane parallel to the line along which the ground is to be worked on.Fig. 2 is a rear view of the same, showing the arrangement of the curvedblades. Fig. 3 is a view of the opposite side to that of Fig. 1. Fig. 4.shows another arrangement of my rotary plow. Fig. 4 is a side elevation,on areduced scale, showing the manner in which the plow is mounted on aplow-frame. Fig. 5 is a plan view of Fig. 4.

Referring to Fig. 1, it is seen that the plow comprises four hoes 1. Thehoe 1 attacks the ground and the removed earth is drawn onto themoldboard 2, which turns up the earth in the same conditions as does anordinary plow and throws it outside the furrow. The sheetiron blades,which are bent so as to form hoes and noldboards, are attached to theaxis by means of iron rods bent at a right angle, the outer edges ofwhich are intended to come into contact with the ground, being beveled.A rotationis given to the plow in the direction of its advancement, asindicated by the arrows.

According to another arrangement (shown in Fig. 4) the hoes are mountedon a metallic hub or disk 3, .to which they are fastened by means ofangle-irons 4. Near the inner circumference 5 of the said disk is placeda single stationary moldboard 6, to which the earth is fed by theseveral'hoes successively. The moldboard may be placed on the right orthe left hand, according to the side on which the right angles, theedges which are intended to come into contact with the grou nd," beingbeveled. A rotation is given to the plow in the direction of the arrow.

When the plow is required to work, it is secured to a frame, as shown,for an example, in Figs. 4; and 5. The hub a) of the plow is keyed on ashaft 6, bearing in a frame 7c,l,the said frame being hinged at n to theshafts m, forming partof a motor-carriage. A spring device, such as q,controls the inclination of the frame is, and consequently the height ofthe plow respectively to the ground. On the end of the shaft 17 oppositeto the hub a is keyed a pulley 0, to which a rotation is given in thedirection D from the motor on the carriage. The plow Works when theframe 70 is displaced horizontally as well as in the direction indicatedby the arrows V or R, provided that the speed of the rotation in thedirection D be suitably controlled.

It must be understood that the rotary apparatus according to the presentinvention for attacking and working the ground is liable to a greatnumber of applications in agricultural appliances as well as in publicworks- 6. g. excavators-and in the latter case slight modifications onlyare required concerning the attachment of the rotary tools. Thecutting-tools may be more or less distant from the center, they may bevaried in number, and their own resistance may be calculated for a givenwork. The form and rigidity of the supports may also be varied and anysuitable material can be employed in their construction and that of theblades without departing from the principle of my present invention.

Having now particularly described and ascertained the nature of myinvention and in what manner it may be carried into eifect, I declarewhat I claim is 1. A rotary plow comprising a hub, radial arms extendingtherefrom and bent at right angles near their ends, and approximatelyS-shaped hoes supported by said radial arms.

2. A rotary plow comprising an axle, a hub mounted thereon, radial armsextending from said hub, and bent at a right angle near their ends, andhoes attached to said radial arms and supported intermediate the pointsbysuch right-angular bends.

In testimony whereof I have hereunto set my hand in presence of twosubscribing witnesses.
